You only wanted to change the last half-second
When the camera ends a little too close, it helps to have a scene you can edit instead of generating the whole clip again.

Take a kitchen shot: the camera moves in from the doorway and ends beside a kettle. The generated room looks good. So does the light. But the camera gets too close, and the kettle fills the frame. You wanted it a little farther back, with some of the table still visible.
Revising the prompt can make a small fix awkward. You wanted to change the ending, but the next clip changes the room, the lighting, and the movement before it. Even the parts you liked have to be generated again.
This is the sort of revision CraftWorld is meant to help with. Build the scene and camera in 3D, then play the preview. Pause at the last frame and move the camera back. Give the opening another second on the timeline. You can watch the change immediately.
Let the reference carry the camera move
In this kitchen example, the preview already shows the route from the doorway to the kettle. When you send it to AI Render, the visual direction can describe rain outside, the room’s lighting, and the kettle’s material. The camera movement is visible in the reference.
Models can still miss it. In the pavilion pair, Seedance 2.5 kept the cut at five seconds and H3 skipped it. Having the planned shot to compare against makes that difference easier to locate.
For a quick style experiment, direct generation works well. When you already know the shot and want to adjust a camera position or a bit of timing, an editable preview can make the revision easier.
